To all whom it may concern.-

Be it known that I, EDWARD B. \ViNTERs, a citizen of the United States,and a resident of Coifeyville, in the county of Montgomery and State ofKansas, have invented a new and Improved RoadJVorking Machine, of whichthe following is a full, clear, and exact description.

This invention relates to road working machines, and more particularlysuch as are used for the grading of roads, and which includesubstantially parallel beams carrying scraper blades adapted to engagethe road surface, and means whereby the pitch of the blades may beadjusted to alter the depth to which they shallsink into the roadsurface.

The object of the invention is to provide a device of the classdescribed, simple and efficient in construction and inexpensive tomanufacture, which is provided with means whereby the pitch of theblades may be altered to suit the road conditions, and which has furthermeans whereby the blades can be drawn at any desired angle over the roadsurface.

Reference is to be had to the accompanying drawings forming apart ofthis specification, in which similar characters of reference indicatecorresponding parts in both views.

Figure l is a plan view of an embodiment of the invention; and Fig. 2 isa longitudinal section on the line 22 of Fig. 1, and shows part of theadjustable construction of the device in different positions in dottedoutline.

In the specific form shown in the drawings, I provide substantiallyparallel beams 1 of wood or the like, which carry blades 2 adapted toengage the surface of a road. Connecting these two beams are links 3having their ends 41 pivotally arranged in brackets 5 on the rear beam.Located on the back of the forward beam by means of bolts or screws 7are two upright posts 6 having their upper and lower ends 8 and 9respectively, bifurcated. The ends 10 of the links 3 are pivotallyconnected at the lower bifurcated ends 9 of the posts by means of pivotpins. The upper ends 8 of the posts extend above the front beam, asshown most clearly in Fig. 2. I further provide on the back of the rearbeam, and secured thereto by means Specification of Letters Patent.

of bolts or screws 12, a plate 13 having a portion 14 laterally andrearwardly disposed. Rigidly secured to the extension 1 1 of the plateby means of rivets, bolts or the like, is a lever 17 having a manualgrip 18 at the upper end thereof. The lever extends rearwardly andupwardly, as shown in the drawings. Slidably located on the lever 17 isa detent 19. A handle 20 is pivotally secured to the upper portion ofthe lever and carries a link 21, which serves to secure it to the detent19 so that as the handle is moved toward the lever the detent is raised,and as it is moved away from the lever, the detent is lowered. I alsoprovide controlling bars 22 which have their forward ends 23 bent andpivotally located in the upper bifurcated portions 8 of the posts 6.These controlling bars further have their rear ends 24 suitably bent sothat they are substantially parallel to one another and serve to carry anotched sector 25, the latter being rigidly and removably securedbetween these ends 2 1 of the bars 22 by means of bolts or screws 26.The detent 19 serves to engage the notches 11 of the sector 25 so thatthe pitch of the bars and their respective blades can be adjusted asdesired. The controlling bars, as will be seen from the drawings,diverge from near the center of the rear beam to the outer ends of theforward beam, thus strengthening the structure against lateral strain.

On the forward end of the front beam are two eyes 27 secured thereto bymeans of bolts or screws 28. Carried by the eyes are two links 29 whichhave their outer ends connected by means of a suitable flexible member30, such as chain or the like. Movably mounted on the flexible member isa loop 31 having a constricted end 32 twisted at right angles to thebody 33, as shown most clearly in Fig. 1. The body of the loop isadapted to be connected to the means employed in drawing the machineover the road, while the constricted end 32 is adapted to engage anydesired link of the flexible member 30, so that the angle of the beamsmay be adjusted with respect to the longitudinal axis of the road. Itwill be understood that the constricted portion grips a link andattaches to the same as long as the pull is exerted by thehorses orother draft means.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. In a road working machine, a forward and a rear beam provided withscraping blades adapted to engage the surface of a road, means forpivotally connecting the said beams, controlling bars pivotallyconnected at their forward ends with the forward beam, a notched sectorrigidly secured to the rear ends of said controlling bars, a projectionat the back of the rear beam, a lever rigidly secured to saidprojection, and means carried by said lever for engaging the notches ofsaid sector.

2. In a road working machine, substantially parallel beams havingscraping blades adapted to engage the surface of a road, posts securedon the forward beam, links pivotally connected with the lower ends ofsaid posts and with the rear beam, controlling bars pivotally connectedat their for ward ends with the upper ends of said posts, a notchedsector rigidly secured to the rear ends of said bars, a lever secured tothe rear beam, and means carried by the lever for engaging the notchesof said sector.

3. In a road working machine, two elongated members having bladesadapted to engage a road surface, posts secured to the forward one ofsaid members, brackets carried by the rear member, links pivotallyconnecting said posts and said brackets, controlling bars, each havingan end pivotally connected to one of said posts, a notched sectorrigidly secured between the free ends of said bars, a plate having alateral extension and 1 located on the rear member, a lever rigidlysecured to said extension, and means on said lever for removablyengaging the notches of said sector, whereby the pitch of said bladescan be altered.

4. In a road working machine, substantially parallel beams provided withscraping blades adapted to engage the surface of a road, brackets on thefront of the rear beam, posts secured on the rear face of the forwardbeam and projecting at their upper ends above said beam, links pivotallyconnected with said brackets and with the lower ends of said posts, aplate secured on the back of the rear beam and having a rearwardextension, a lever secured to the said extension, controlling barshaving their forward ends bent and pivotally connected with the upperends of said posts, the said bars converging rearwardly and extending attheir rear ends above the rear beam near the center thereof, the rearends of said bars being bent and ar ranged substantially parallel witheach other, a notched sector secured between the rear ends of said bars,and a detent carried by said lever and adapted to engage the notches ofthe sector to adjust the pitch of the beams and their respective blades.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
